Method of producing fabric reinforcing matrix for composites

摘要

A reinforcing matrix is produced using a plurality of regulating members (pins) removably arranged in rows in a predetermined direction on a base. Yarns are woven between the pins on the base repeatedly looping back and forth between spaced apart positions to form a yarn lamination consisting of a plurality of yarn layers over the base. The yarns forming the yarn layers are arranged in at least two directions. Thereafter the yarn lamination is removed from the base together with the pins. Then the pins are replaced sequentially in rows arranged in the predetermined direction with separate vertical yarns which are inserted into the yarn lamination so as to form loops. A selvage thread is inserted in the predetermined direction through the loops of the vertical yarns.
